Escalation Timer Begins when Task is created or Reminder Timers finish (Flexi)?

Hello,

I have an easy one here, that I'm sure someone could answer and earn post-points rather quickly... Within the Flexi Task, I'm trying to determine what to set my Escalation timer to when also using Reminders. I'm unclear if the Escalation time starts AFTER the last reminder concludes, or if the Escalation timer is based on when the task was created.

Example, reminders at days 10 and 20, escalate at day 24. Should my escalate timer be 4 or 24?
